On the new generation of memory chips, many domestic companies have also followed up MRAM, PRAM and PCM phase change memory chips. Recently, Jiangsu Times Whole Core Company released phase change memory programmable read-only memory, 2Mb size, which is said to be following Samsung. A few companies that have mastered the core technology of phase change memory chips after Micron.
In the current memory chips, DRAM memory and NAND flash memory are mainly in the hands of Samsung, Toshiba, Micron, SK Hynix and other companies. The domestic NAND flash memory has just started, and DRAM memory is still in the laboratory, and it has not yet been mass-produced.
In terms of phase change storage, Samsung, Micron and other companies have previously released their own PCM chips. Intel's 3D XPoint memory chips are said to be based on the PCM principle, but the official has not been clear about this.
According to the official website, Jiangsu Times Core Semiconductor Co., Ltd. was formally established in October 2016. The company's shareholders include Jiangsu Times Whole Core Storage Technology Co., Ltd. and Huai'an Yuanxing Investment Co., Ltd. The company is committed to the development and production of storage products equipped with the latest PCM technology. Jiangsu Huai'an PCM production project has a total investment of 13 billion yuan, the first phase investment of 4.3 billion yuan, Huai'an Yuanxing Investment Co., Ltd. invested 1.6 billion yuan to account for 44%. Jiangsu Times Whole Core Storage Technology Co., Ltd., with its own intellectual property and cash contribution, accounted for 56% of the shares, of which intellectual property mainly includes the company's proprietary technology and patents.
Although the company claims to be the third company in the world to master PCM phase change storage technology, with independent intellectual property rights, but their technology source is actually IBM authorized, and began to cooperate with IBM in 2009, generated 275 authorizations from IBM The patents, 92 independent intellectual property rights patents and nearly 1,000 non-patent proprietary technologies were officially transferred to Huai'an, Jiangsu.
In any case, the era-core phase change memory chip of the era is relatively small, but it is also the first time in domestic reports to mass-produce PCM chips, the significance of technological progress is still very significant.
